In a recent study of Black American women, low levels of vitamin D appeared to be related to increased incidence of COVID-19 infection.

Several forms of public messages can increase vaccination intentions, but messaging that emphasizes personal health benefits has the largest impact.

Subtle differences in perception during late-teen years can predict the development of hallucinations, delusions, and, in some instances, psychosis later in life, according to new research.

Madagascar is renowned for its unique and varied biodiversity, which spans dry grasslands, wet rain forests, mangroves and deserts. This variety, combined with the island’s isolation and size, has fostered distinctive assemblages of plants and animals,…

Hydrogen peroxide reacts with copper to produce hydroxyl radicals with strong antibacterial properties. However, this requires high copper concentrations because two copper atoms have to come close together, which occurs by chance. Now, scientists have…

Every year, 3.5 million metric tons of sodden diapers end up in landfills.

A bird’s-eye view may take on new meaning thanks to new research. Scientists found that a protein in bird’s retinas is sensitive to the Earth’s magnetic field thus guiding its migratory patterns. That finding could be key to Army navigation of both aut…

Researchers have decoded the chromosomal-level genome of a deep-sea gutless tubeworm and the genome of its co-living ‘partner’ — a kind of bacteria that provide nutrients they generate from inorganic compounds to the worm for the first time, explainin…

A new study finds that the disconnect between how old we feel and how old we want to be can offer insights into the relationship between our views on aging and our health.

When a compound of manganese and sulfide (MnS2) is compressed in a diamond anvil, it transitions from an insulator into a metallic state and back into an insulator. This is accompanied by unprecedented decreases in resistance and volume across an extre…

Researchers have discovered that decisions based on visual information, which involve a complex stream of data flowing forward and backwards along the brain’s visual pathways, is broadcast widely to neurons in the visual system, including to those that…

Researchers have demonstrated a low-cost technique for retrieving nanowires from electronic devices that have reached the end of their utility and then using those nanowires in new devices. The work is a step toward more sustainable electronics.

A model of the eastern California forests of the Sierra Nevada looks at the longer-term future of wildfires under future climate change scenarios. Results show an initial roughly decade-long burst of wildfire activity, followed by recurring fires of de…

A new technology for cellular immunotherapy showed promising anti-tumor activity in the lab against hard-to-treat cancers driven by the once-considered “undruggable” KRAS mutation, including lung, colorectal, and pancreatic.

Researchers discovered that although the brain regulates feeding for pleasure and for hunger through serotonin-producing neurons in the midbrain, each type of feeding is wired by its own independent circuit that does not influence the other type of fee…

Researchers show that restoring normal function of the molecular clock suppresses tumor growth in advanced neuroblastoma and can make tumors more sensitive to conventional chemotherapy.

Black holes, detected by their gravitational wave signal as they collide with other black holes, could be the product of much earlier parent collisions. Such an event has only been hinted at so far, but scientists believe we are getting close to tracki…

Women leaders must often battle sexist stereotypes that label them ‘too emotional’ for effective leadership. A surprising new study shows that when they express calm, happy emotions, however, women are perceived as more effective leaders than men. The …

From art to religion to land use, much of what is deemed valuable in the United States was shaped centuries ago by the white male perspective. Fish, it turns out, are no exception. A study explores how colonialist attitudes toward native fishes were ro…

Astrophysicists have discovered the presence of transverse rotation (in the plane of the sky) in three dwarf spheroidal galaxies, a very faint type of galaxies and difficult to observe, which are orbiting round the Milky Way; this helps to trace their …
